The difference between oil bearing and self-smooth bearing
1. Oil bearing is a combination of metal powder and contains 10-40% of structural voids; the inlaid self-bearing bearing base is centrifugally cast,of which the base density is relatively high, the bonding strength and the service life are both higher than that of oil bearings.
2.Smooth oil is raw material of the oil bearing and the oil film of that has a satisfactory thickness, whic eliminats the direct contact between the two conflicting surfaces. Therefore, there is only conflict between the liquid molecules, so the conflict coefficient is very small (f = 0.001 ~ 0.008), which significantly reduces conflict and wear; and the smooth raw material embedded in the smooth bearing is solid smooth material, even in oil-free circumstances, the excellent smoothing effect that can still take effects, ensures smoothness ceaselessly and sustainably, and its useful smooth life and the life of the substrate together;
3.The smooth oil in the oil-bearing bearing is volatile. The smooth oil film is easy to be thrown away under high temperature and high pressure so that the smoothing effect cannot be obtained;In the graphite copper sleeve, the solid smoothing agent is transported or reversed to the conflicting surface through the conflict, and the solid smoothing film on the conflicting surface forms a smooth, solid, solid adhesion and uniform cover, which greatly reduces the Conflict wear. As the conflict progresses, the embedded solid smoothing agent is continuously supplied to the conflict surface, ensuring excellent smoothness to the conflict pair during long-term operation.
